A summary of this thread’s drag slips was made for reference then plotted against the sim. The sim’s curves have been set at sea level for continuity. References suggest up to 1200 feet altitude doesn’t have a major effect on the performance of turbocharged engines, which may be why correction factors below this altitude aren’t common.

I have included split times for the intervals to allow a more detailed look at performance as it removes rollout differences, (a summary of their usefulness can be found at
http://www.motorsportsvillage.com/timeslip.html ).
I’m also including a template graph for the 60 mph interval. By identifying the estimated reference HP curve for the 660’ and 1320’ times, 0-60 mph times can be approximated. Examples – K320 and XenaBimmer are roughly at +25 HP for both distances, so that would put their time around 5.250 sec on the 60 mph graph. Jamoka3 tuned is around the sim’s stock line, so that run appears close to 5.525 sec, whereas his stock was at the -30 HP reference line which would equate to 5.975 sec.
Considering the number of variables which can influence the end result (temp, barometric pressure, altitude, weight, tires, track ...) if a stock run can be obtained before tuned runs a reference point for that individual day it might prove helpful when trying to assess tune changes or comparing runs on different days.
